Be it known that I, EMIL BALZER, a citizen of the United States, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Car-Couplings, of which the following is a specification.

My invention relates to car-couplings; and

coupling from top of a car, the coupling being effected automatically by the impact of the draw-heads when the cars are pushed together.

My invention is illustrated in the accompanying drawings, in which Figure 1 is a vertical section showing the ends of two cars with their couplings set for action. Fig. 2 is a vertical section ,ofthe draw-heads coupled together. Fig. 3 is ahorizontal section of the draw-heads uncoupled. Fig. 4 is a top view of the chain-bracket. Fig. 5 is a side elevation and partly a section. Fig. 6 is asection on line (3 6 in Fig. 5. Fig. 7 is a side elevation of the hook. Fig. 8 is a top View of the sliding handle. Fig. 9 is a side View thereof. Fig. 10 is a cross-section on the line 10 10 in Fig. 9.

Similar letters of reference in the various views indicate corresponding parts.

The draw-heads A A of the cars are secured in the usual manner to the truck of the car and act against the buffer-springs B. In the end of each draw-head are formed two cavities a and a, the smaller one, a, being adapted to hold the coupling-link ai secured therein by the pin a in a substantially horizontal position. The otherlarger cavity, a, is designated to receive the coupling-link a when the draw-heads are pushed together, and through it passes the coupling-pin a, being automatically released and dropping in the hole a at the same time.

The coupling-pin a is suspended on chain (1' and red at over bracket 0 secured near the top of the car, sloped downward, and havin g a forked slide 0 screwed to its upper su rface by screws 3. The chain d, on which coupling-pin a is hung, is attached to handle D, sliding on the bracket between the tines of the forked slide 0 and passes over pulley 0,

set on a stud in the vertex of the bracket 0 When the coupling is open, the sliding handle is held at the top of the bracket 0 by hook c of the handle a, the pin entering the hole d, provided for this purpose in the elongated base of the handle D. Handle 0 is secured to (or made in one piece with) push-rod O, sliding along the wall of the car through holes 0 providedv for this purpose in the flanges of brackets C and (J and resting on the casing of the draw-head shanks. Near the lower end of the rod C is attached to it the chain c, passing over the pulleys c 0, set in the lower bracket 0, and fastened at its other end to the draw-head. Thus when the draw-heads are forcibly joined push-rod O is lifted, hook c is disengaged from the hole cl, and the handle D. being thus released pin (0 drops and effects the coupling by arresting link (t in. the cavity a, as above described.

On top of the draw-heads over the hole a is provided a boss a to guide the coupling-pin a", so that it will not slip out of hole a when lifted.

To uncouple the cars, it is only necessary to pull up the handle D on the incline, thus lift ing the c'ouplingpin ctand releasing thereby the link a. Then red C is lifted by the handle 0 and the hook c inserted again in the hole 01 in the handle-piece D. This must be done on both adjoining ears. There, however, may be a line stretched over the roofs of the cars and the handles D secured thereto, and then the uncoupling may be done from any point of the car by pulling this line upward.

I claim as my invention and desire to secure by Letters Patent 1. In a car-coupling, the combination of a draw head, having two cavities on the same plane, a coupling-link, set in one of these two cavities and a pin set vertically in the drawhead and engaging the link, holding it securely therein, in position to enter the corresponding cavity of an opposite draw-head, a drop-pin, sliding in a hole, passing vertically through the othercavity, and adapted to arrest the link of an opposite draw-headthereby coupling the draw-heads together, a bracket secured to the wall of the car above the draw head, a grooved pulley set in the bracket over the pin-hole, a chain attached to the dropping-pin and passing over the pulley, a

forked guide, secured to the bracket, a sliding handle, attached to the chain, sliding on the bracket between the tines of the forked guide, and having a hole in its baseplate, adapted to receive a hook, whereby the droppin g-pin may be lifted above the cavity in the draw-head and held in uplifted position.

2. In a car-coupling, the combination of a draw-head, having two cavities on the same plane, a coupling-link, set in one of these two cavities and a pin set vertically in the drawhead and engaging the link, holding it securely therein, in position to enter the corresponding cavity of an opposite draw-head, a drop-pin, sliding in a hole, passing vertically through the other cavity, a bracket secured to the wall of the car above the draw-head, a grooved pulley set in the bracket over the pin-hole, a chain attached to the droppingpin and passing over the pulley, a sliding handle attached to the chain, having a hole in its base-plate and adapted to be held in uplifted position by a hook, a push-rod, adapted to slide up and down along the wall of the car, a handle connected to the upper end of the push rod and having a hook adapted to enter the hole in the base-plate of the lifting-handle, a bracket secured to the wall of the car above and in near proximity to the draw-head, grooved pulleys set in the bracket, a chain secured to the lower end of
